What Leiblein does

Leiblein GmbH is a German family-owned industrial equipment manufacturer founded in 1953 and headquartered in Hardheim, Germany, specializing in solid/liquid separation technology for water treatment, cooling lubricant processing, and sludge dewatering. The company designs, manufactures, and commissions a comprehensive portfolio of 16 core product categories spanning rotary screens, lamella clarifiers (Schrägklärer), flotation clarifiers, vacuum and pressure belt filters, continuous sand filters (FlowSand-Filter), gravity filters with automatic siphon backwash, magnetic separators with 360° permanent magnet technology, coalescence separators (SPKA/Ölex variants), centralized cooling lubricant systems, the mobile ClearUp 250 filter trolley, and dewatering containers — covering all major physical separation techniques (sedimentation, flotation, filtration, magnetic separation).

The company's underlying technology is rooted in physical separation process engineering, with notable proprietary features including automatic gravity filters that achieve clear water values of 0-5 mg/l filterable substances without energy or control systems, coalescence separators for simultaneous foreign oil and solids separation, and magnetic separators with throughputs up to 900 l/min. Leiblein operates from a substantial manufacturing footprint including a 2,400 m² production hall with six overhead traveling cranes (70t total lifting capacity), an in-house pickling line, welding robot systems, and a 297.33 kWp photovoltaic installation — enabling vertically integrated custom equipment production.

The business model is B2B enterprise equipment sales targeting ten industrial verticals (metal processing, gravel/sand, recycling, glass, ceramics, chemical, steel, energy, construction/tunneling, and food processing), with revenue generated through one-time equipment sales, custom turnkey plant systems, engineering/professional services, and pilot plant rentals. GTM is direct enterprise field sales with consultation-based selling and a distinctive pilot-plant rental program that allows customers to validate equipment before purchase. Pricing is fully custom-quoted with no public disclosure; pilot plant rental supports bottom-of-funnel conversion. Customer logos and references span Switzerland (AlpTransit Gotthard tunnel) and Italy (Lago Maggiore groundwater remediation), confirming a regional European footprint beyond Germany.
